I would imagine that quite a few men who joined the military after 9/11 did so because they wanted to kill some radical Muslims. But, as to your comment, Pat Tillman isn’t here to defend himself, so I don’t see why you would see fit to mention this. He went and (voluntarily) did some very dirty work for this country, and for our way of life. Lost his life doing it, in fact. If that’s not a hero, I don’t know what is.
